Problems solved by technology
Because the curved wall, curved roof and factory building are consolidated together, the structure does not consider the vibration effect and fuel fire caused by the impact of the aircraft, which may easily cause damage or functional failure of the internal equipment of the factory building.

Embodiment Construction
[0027] The present invention will be described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described in the present invention are only for explaining the present invention and not for limiting the present invention.
[0028] According to the requirements for the integrity and cooling of the reactor and spent fuel in the acceptance criteria in the regulations and guidelines, the reactor building, spent fuel storage building, electrical instrumentation and control building (including the main control room where the operator handles the accident and Important instrument control cabinets), special safety workshops that perform cooling functions and their (power supply, water intake) functions support the design and protection of plant structures.
[0029] Figure 1A , Figure 1B , Figure 1C It is a schematic diagram of several specific implementations of an overall protection scheme for a nuclear power plant ag...

Abstract
The invention relates to a method and system for preventing a nuclear power plant from being hit by a large commercial airplane. The method protects an anti-hit structure arranged in a reactor plant,a spent fuel storage plant and an electrical instrument control plant. Meanwhile, two rows of redundant special safety plants and functional supporting plant structures of the redundant special safetyplants are fully arranged in a physical-isolating mode relative to the anti-hit structure, and protective structures are arranged at positions of openings or holes which may exist in the anti-hit structure. The method and system realize the comprehensive protection of four effects (namely, overall stability, local penetration effect, vibration effect and fire effect) generated by the hit of the large airplane, the balance of economy and the implementability of engineering are considered, and the application prospect is good.
Description
Technical field [0001] The invention belongs to the external event protection design technology of nuclear power plants, and specifically is a protection method and system for nuclear power plants to resist the impact of commercial large aircraft. Background technique [0002] After the 9 / 11 incident in the United States, international attention was paid to the possibility of large commercial aircraft attacking key national facilities, including nuclear power plants. Countries also have relevant requirements for applicants for new nuclear power plants, including the United States Federal Regulations 10CFR50, and the requirements of the Western European Nuclear Regulatory Commission WENRA. The domestic nuclear safety regulations HAF102 also clearly require that nuclear power plants are designed to consider the possibility of malicious attacks by commercial aircraft, and through evaluation to prove that the design can maintain the cooling of the reactor core or the integrity of the...
